A system that stores plural reference measures, each reference measure corresponding to measured transitions of one or more video objects of plural successive pictures corresponding to a video scene, receives first and second measures of plural successive pictures corresponding to a first video scene received from a remote device, the first and second measures corresponding to measured transitions of a video object of the first video scene, compares the first and second measures with the stored plural reference measures, and indicates to the remote device whether a threshold percentage match exists between the first and second measures and one of the stored plural reference pictures.
